No I mean it's only been tested on a machine with a 32-bit registers. It's the integer manipulations I want to double check - there are some expressions which could conceivably be optimized in a way that would fail if 64-bit registers are used - I believe they shouldn't do so if the standard is strictly followed - but sometimes compilers can play a bit fast-and-loose when optimizations are turned on. If necessary I have a fallback, but let's see if there's an issue first.

I'm confused. As I'm sure we all know, 64 bit amd x86_64 uses 64 bit pointers, but int is still 32 bit.
It uses a mix of 32 and 64 bit integer operations, for example "complement a 32 bit int, then promote to 64 bits and add". Reverse the order of operations and the complement will do the wrong thing. Any clearer? ;-) John.
